When it comes to keeping your Lexus running smoothly, understanding the type of battery your vehicle uses is crucial. Whether you drive a luxurious ES 350 or a versatile RX 350, the battery plays a vital role in performance and reliability. In this article, our team at Longo Lexus will explore the different batteries Lexus uses, outline how to identify when it’s time for a replacement, and provide a handy guide for replacing your battery, ensuring your Lexus continues to perform at its best.
What Kind of Batteries Does Lexus Use?
Lexus vehicles use various battery types, tailored to meet the specific needs of its diverse lineup. Learning about these batteries can help you make informed decisions regarding maintenance and replacement.
Lead-Acid Batteries
Lead-acid batteries have been the standard for conventional vehicles for decades. Lexus uses these batteries primarily in its gasoline-engine models. They provide reliable starting power and are relatively inexpensive compared to other battery types. Lead-acid batteries come in two main varieties: flooded and sealed. Flooded lead-acid batteries require regular maintenance, while sealed batteries offer more convenience with minimal upkeep. Both types effectively power your Lexus and keep it running smoothly.
Nickel-Metal Hydride Batteries
For hybrid models, such as the Lexus RX 450h, you’ll find nickel-metal hydride (NiMH) batteries. These batteries store energy generated during braking and use it to assist the gasoline engine, improving fuel efficiency and reducing emissions. NiMH batteries have a longer life span compared to traditional lead-acid batteries, making them an excellent choice for hybrid vehicles. Their ability to handle deep discharges and recharge efficiently contributes to the overall performance of Lexus hybrids.
Lithium-Ion Batteries
Lexus has also started incorporating lithium-ion batteries in some of its newer hybrid models. These batteries offer greater energy density, meaning they can store more energy in a smaller and lighter package. This characteristic enhances performance and efficiency, making them ideal for today’s advanced hybrid technologies. Additionally, lithium-ion batteries have a longer life span and require less maintenance, making them a popular choice among automakers looking to push the boundaries of electric and hybrid vehicle performance.
How To Determine When It’s Time for a New Lexus Battery
Knowing when to replace your Lexus battery helps you avoid unexpected breakdowns. Below are seven signs that it’s time for a new battery.
Warning Lights
If your dashboard’s battery warning light turns on, it’s time to investigate. Ignoring this warning can lead to more severe issues down the road, so we recommend visiting us to get a thorough diagnosis.
Slow Engine Crank
If the engine is slow to crank when you turn the key or push the start button, it could mean your battery is weak. You might notice this on cold mornings or after your car has been idle for a while. A sluggish start means your Lexus may need a new battery.
Electrical Issues
If you experience problems with your lights, power windows, or other electrical components, your battery might be failing. A weak battery can’t supply enough power to run these systems effectively, leading to frustrating malfunctions.
Age of the Battery
Most batteries last between three and five years. If your Lexus battery is older, consider getting it tested. Even if it seems to work fine, age can affect performance, especially in extreme weather conditions.
Corrosion
Check the battery terminals for any signs of corrosion. If you see a white, chalky substance, it indicates a chemical reaction that can hinder performance. While cleaning the terminals can temporarily help, it might be a sign that you need a replacement.
Unusual Smells
If you notice a rotten egg smell coming from your battery, your battery could be leaking. This situation can be dangerous and requires immediate attention. Don’t hesitate to bring your Lexus to us for a thorough inspection.
Swelling or Bulging
A swollen battery case often indicates internal damage or overheating. If you see any physical deformities, stop using the battery and reach out for assistance. Safety comes first.
